Abstract
Claims
1. An oil mist filter element (a), comprising: a top cover having an annular disc, a flow collector located at the center of the disc, a plurality of flow guides equally spaced on the disc and extending radially outward from the outer periphery of the flow collector, a plurality of guide grooves formed between pairs of flow guides, and at least two holding portions spaced apart on the outer periphery of the disc and each connected to at least one flow guide, wherein the top surface of the aforementioned holding portions does not extend beyond the bottom of the guide groove; a bottom cover being an annular hollow body having a through hole located at the center, and the outer diameter of the bottom cover being larger than the outer diameter of the top cover; and a filter media assembly connected in an annular shape between the top cover and the bottom cover.
2. The oil mist filter element (a) as described in claim 1, wherein, The top cover has four grips, arranged symmetrically in pairs and extending radially outward from the disc body.
3. The oil mist filter element (a) as described in claim 1, wherein, The outer edge of the grip is arc-shaped.
4. The oil mist filter element (a) as described in claim 1, wherein, The top cover has a first annular groove on a bottom surface of the disc body, and the bottom cover has an annular body and a second annular groove on a top surface of the body. The maximum and minimum diameters of the second annular groove of the bottom cover are both greater than the maximum and minimum diameters of the first annular groove of the top cover, respectively.
5. The oil mist filter element (a) as described in claim 1, wherein, A circular arc slope connects one side of the aforementioned guide section and the guide channel.
6. The oil mist filter element (a) as described in claim 1, wherein, The flow collection part of the top cover is a bulging, rounded shape, and the aforementioned flow guide extends outward from the periphery of the flow collection part at an angle of 70 degrees.
7. The oil mist filter element (a) as described in claim 1, wherein, The filter media assembly includes an outer mesh, an air guide mesh, a settling mesh, an interwoven mesh, a middle layer of diamond mesh, an oil-water separation layer, and an inner mesh.
8. The oil mist filter element (a) as described in claim 1, wherein, The aforementioned grip portion extends radially outward from the outer periphery of the disc body, such that the corresponding aforementioned guide portion extends to the top surface of the aforementioned grip portion.
9. The oil mist filter element (a) as described in claim 1, wherein, The aforementioned gripping parts are pivotally connected to the outer periphery of the disc body and can pivot between a pull-out position perpendicular to the disc body and an installation position parallel to the disc body.
10. The oil mist filter element (a) as described in claim 9, wherein, Each of the aforementioned gripping parts is provided with a locking block, and the disc body forms a positioning groove for each locking block of the aforementioned gripping part, so that the aforementioned gripping part can be limited to the installation position and cannot be pivoted arbitrarily.
11. The oil mist filter element (a) as described in claim 9, wherein, There are two grips, which are semi-circular in shape.
12. The oil mist filter element (a) as described in claim 9, wherein, The aforementioned grip portion further has a plurality of extended guide sections disposed on the top surface and connected to the end of the aforementioned guide portion.
